Taking fix#29038:
Make possibility to dramatically increase the step during iteration on the curve when the global resolution of the curve is too small.
Correct the functions FindParameters, FindBestSolution, FindDistPC.
The change caused improvement of the test case "boolean bfuse_complex E4", so the bug #27697 has been fixed.
The change caused dramatic improvement of the performance of the test "bugs modalg_7 bug27160", and the bug #29080 has been fixed.
BOPAlgo_PaveFiller: Add method for forced Edge/Face intersection to look for additional cases of coincidence.
BOPAlgo_BuilderSolid: Avoid creating solids from unclassified faces as such solids will be useless. Just warn user about unclassified faces.
partially disabled; fixed frustum culling bug].
Graphic3d_RenderingParams::ToShowStats - new option displaying rendering statistics.
OpenGl_FrameStats - new class for accumulating frame statistics.
OpenGl_Context::FrameStats() provides an access to the frame stats
used for currently rendered context.
OpenGl_View::Redraw() and OpenGl_View::RedrawImmediate()
resets counters within OpenGl_Context::FrameStats().
OpenGl_Layer::UpdateCulling() - simplified resetting of culling state for cullable structures.
# Conflicts:
# src/OpenGl/OpenGl_FrameBuffer.cxx
OpenGl_LayerList::Render() now handles new option Graphic3d_RenderingParams::ToEnableDepthPrepass
which prepends additional pass to rendering pipeline filling Depth Buffer in advance.
Graphic3d_ZLayerSettings::CullingDistance() and ::CullingSize() - added
new properties configuring culling of small and distant objects, disabled by default.
OpenGl_BVHTreeSelector now handles size culling and distance culling in addition to frustom culling.
Font_FTFont now uses fallback fonts for characters from unsupported Unicode subsets,
managed by Font_FTFont::ToUseUnicodeSubsetFallback()
and Font_FontMgr::ToUseUnicodeSubsetFallback() option, enabled by default.
The fallback list includes common font families for Chinese, Korean and Japanese languages.
Font_FTFont::RenderGlyph() now supports FT_PIXEL_MODE_MONO input format used by some CJK fonts.
OpenGl_Font::createTexture() now limits single texture size to circa 4096 glyphs.

Font_FontMgr::FindFont() and command "vfont -find" have been extended with -strict option
to check whether the given font is actually registered or not.
Font_FTFont::Init() - added constructor from memory buffer.
Second Font_FTFont::Init() override has been renamed to Font_FTFont::FindAndInit()
to avoid ambiguity between two similar methods taking full font path and font name as string.
# Conflicts:
# src/AIS/AIS_Dimension.cxx
# src/OpenGl/OpenGl_Text.cxx
Font_FontMgr has been redesigned to:
- Store fonts in a map instead a list.
- Allow mapping multiple fonts to a single alias.
- Log informative message about usage of non-requested font (fallback).
- Register all font files within standard folders on Linux when "fonts.dir" is not found.
- Prefer specific alias ("serif") as default fallback font instead of arbitrary one in a system.
A couple of obsolete and broken font aliases have been removed;
instead, new aliases of fonts popular on Linux platform have been added.
Font_NameOfFont.hxx has been extended with more neutral aliases
"monospace", "serif", "sans-serif", "cjk" and "korean".
Font_FontAspect enumeration values have been renamed Font_FA_ -> Font_FontAspect_
with old values preserved as alias.
Font_SystemFont has been extended with a list of paths to Font_FontAspect styles,
so that entire Font Family is now defined within a single Font_SystemFont instance.
Non-resizable fonts are now ignored by Font Manager.
Font_BRepFont now uses a dedicated algorithm for text-to-BRep transformation instead of relying on ShapeFix.
It orders wires based on wire classification, analyzes internal zones and creates a few faces (if needed).
TKService dependency from TKShHealing has been dropped.
Font_BRepFont::buildFaces() backport.
Fixed FT_Get_Kerning misuse within Font_FTFont::AdvanceX()/Font_FTFont::AdvanceY().
Font_FTFont::loadGlyph() has been corrected to not return TRUE
in case if method called with 0 argument second+ time.
Font_SystemFont - added a new property SingleStrokeFont().
Font_BRepFont::renderGlyph() has been extended to not close contours
when flag SingleStrokeFont() has been set.
Sometimes the algorithm of purging of extra points in the walking line makes enormous difference in distance between two neighbor segments of the line. This badly impacts the quality of approximation result. This patch balances the difference in distances by forbidding deletion of some points.

Before the fix, BRepAdaptor_CompCurve considered the input wire to be periodic with period LastParameter()-FirstParameter().
Now, method IsPeriodic will always return FALSE because it is impossible to obtain correspondence between the members of BRepAdaptor_CompCurve class and its periodicity status.
New behavior has been documented in upgrade-guide.
The following improvements have been implemented in BRepLib_MakeWire class to make it more reliable:
1. Quit adding edges of a wire into result if the current edges have not been added. Return NotDone status.
2. Allow merging not only bounding vertices (connected to only one edge) but also the middle ones, so the multi-connected vertices may appear in the result.
Test case for the issue.
Using of input tolerance has been eliminated in Geom2dInt_GInter algorithm called from BRepClass_Intersector::Perform(...) method. Now, the input tolerance is used only for check ON-status of classification.

Creation of IntPatch_Points is forbidden in tangent-zones exceptionally domain boundaries of intersected surface.
(cherry picked from commit 2123a44c2595633288e208a352050592710782f5)
Now, bounded IntPatch_Points are found in case when starting points are used in intersection algorithm. Before the fix, these points were not looked for (even).

Boolean Operations - when checking two faces with the same bounds on Same Domain, take into account possible deviation of the edges from the faces surfaces.
Test cases for the issue.
(cherry picked from commit 8a7476a62292cb359f2459138e8a267d1aa07ce2)
Strengthening of the criteria of the parallel status of the curves by additional checking if the ends of the curves do not diverge.
Test cases for the issue.
Documentation is added in a new "Inspector" page of "User Guides".
Inspector plugins has some improvements by the documentation needs.
New DRAW scripts are implemented for 'tinspector' command.
Simple offset algorithm (BRepOffset_MakeSimpleOffset) is improved to handle the case when bspline surface has imprecise singularity at one of sides (when side is degenerated but not exactly to one point).
In such case, the algorithm tries to collapse all poles of singular side of the surface to the same point; this allows avoiding flapping of normal due to small fluctuations of surface.
If face being offset contains degenerated edges, then check for singularity is done using position and tolerance of corresponding vertices.
In addition, each side is checked with some user-defined tolerance (by default Precision::Confusion()); this helps to process cases when no edge is located at that side or if such edge is not encoded as degenerated.
New parameter Tolerance is introduced for that in BRepOffset_MakeSimpleOffset class.
Tests added:
bugs modelg_7 bug28968 - on isolated faces as reported in the issue, mostly for visual check (absence of loops)
offset simple F01-05 - on original shells, checking tolerances of resulting shell
1. A tool to annotate items in the hierarchical product structure was added. The tool is located under
fixed label 0:1:9. It operates two basic entities: notes and annotations located under 0:1:9:1 and 0:1:9:2
hives correspondingly. A note is an attribute derived from base class XCAFDoc_Note that is attached to a separate
label under the notes hive. An annotated item is represented by XCAFDoc_AssemblyItemRef attribute
attached to a separate label under the annotated items hive. Notes are linked to annotated items by means of
XCAFDoc_GraphNode attribute, where notes play parent roles and annotated items - child roles.
2. XCAFDoc_AssemblyItemRef defines a weak reference to a label with optional attribute GUID or sub-shape index.
3. A capability to store note/annotation labels in XCAFDoc_ViewTool was added.
4. XDE User guide was updated
Tests are added to control output and performance of progress indicator (bugs fclasses bug28478 and perf fclasses progress, respectively).
Implementation of class Draw_ProgressIndicator is improved to update indicator basing on achieved total progress (1% by default) instead of elapsed time since last update.
Method OSD_Chronometer::Restart() is fixed to actually reset the counter.
DRAW command readstl is improved to show progress indicator if configured (by command XProgress).
Description of class Message_ProgressIndicator is updated; code example is added in description of Message_ProgressSentry.
Synchronization of the ShapeAnalysis_Edge behavior with the BRepCheck_Edge by adding check for 2d curves on planes.
Implementation of the BRep_Tool::CurveOnPlane method to avoid code duplication for making PCurve of the edge on planar face.
Handling of degenerated points (with all derivatives zero) in GeomEvaluator_OffsetSurface is improved by iterative movement towards middle of the surface (extension of one-step approach implemented earlier in #28112).
