ba00aab7a0 0029528: Visualization, TKOpenGl - allow defining sRGB textures
OpenGL rendering is now done into sRGB framebuffer.
OpenGl_ShaderManager::prepareStdProgramFboBlit() has been extended
by programs resolving MSAA texture and applying gamma correction as fallbacks.

Quantity_Color definition has been modified to store RGB components
in linear color space within Quantity_TOC_RGB type.
Standard colors defined by Quantity_NameOfColor enumeration has been updated accordingly.
New Quantity_TOC_sRGB type has been introduced to handle RGB components in non-linear sRGB color space.

OpenGl_TextureFormat class definition has been moved to dedicated files.
New method OpenGl_TextureFormat::FindFormat() replaces OpenGl_Texture::GetDataFormat().
New method OpenGl_TextureFormat::FindSizedFormat() replaces OpenGl_FrameBuffer::getColorDataFormat()
and OpenGl_FrameBuffer::getDepthDataFormat().

Graphic3d_TextureRoot::IsColorMap() - introduced new property defining
if RGB(A)8 image formats should be loaded as sRGB(A) textures or as data RGB(A) textures.
OpenGl_Texture initialization methods have been extended with new theIsColorMap argument.

vreadpixel - added argument -sRGB printing color in sRGB color space.

Test cases have been updated to new sRGB rendered results.

aaf8d6a98d 0030969: Coding Rules - refactor Quantity_Color.cxx color table definition
The table of named colors has been compressed and moved out
from Quantity_Color.cxx into Quantity_ColorTable.pxx.

Quantity_NameOfColor - grayscale enumeration values have been re-ordered to fix discontinuity.
Duplicating colors has been merged within enumeration:
  CHARTREUSE=CHARTREUSE1, GOLD=GOLD1, GREEN=GREEN1, ORANGE=ORANGE1,
  ORANGERED=ORANGERED1, RED=RED1, TOMATO=TOMATO1, YELLOW=YELLOW1.
Added aliases to several other common colors:
  BLUE=BLUE1, CYAN=CYAN1, LIGHTCYAN=LIGHTCYAN1, MAGENTA=MAGENTA1.

Quantity_Color class definition has been cleaned to follow OCCT coding style.
Quantity_Color now stores NCollection_Vec3<float> as class field instead of separate components.
Removed unused class Quantity_ColorDefinitionError.

New methods Quantity_Color::Convert_LinearRGB_To_sRGB() and Quantity_Color::Convert_sRGB_To_LinearRGB()
converting RGB components from linear to non-linear sRGB colorspace and vice versa.
Image_PixMap::PixelColor() and Image_PixMap::SetPixelColor() methods have been extended
with an optional argument for performing linearization/delinearization of 8-bit sRGB pixel formats.

Draw Harness command AISColor has been corrected to take color name instead of enumeration index.

d4efee2bfa 0029356: Modeling Algorithms - GCPnts_TangentialDeflection hangs on specific curve
While UV Iso parameters are obtained in StdPrs_Isolines, UV limits should be applied only if face bounds has infinite values.
In the issue case, the UV values are greater than UVLimits and not infinite. This fix makes possible to have correct Iso lines in presentation without modification of UV limits beforehead.

d2e6068829 0028646: Draw Harness, ViewerTest - rename vsetfilter command with vselfilter
TopAbs::ShapeTypeToString() is now used instead of duplicating TopAbs_ShapeEnum printing code.
vselmode now accepts shape type string for activating standard AIS_Shape selection modes.

14c4193d11 0028390: Visualization, AIS_InteractiveContext - add topmost-only picking strategy
AIS_InteractiveContext::PickingStrategy(), added new property
defining picking strategy SelectMgr_PickingStrategy.
Strategy SelectMgr_PickingStrategy_OnlyTopmost allows picking only
topmost detected entity not rejected by Selection Filters.

52f99d93a9 0022877: Implementation of DRAW commands for non-regression testing:
- TKIVtkDraw toolkit provides IVtk packages functionality in DRAW.

- it allows to create VTK interactive view in regular or virtual mode (virtual windows),
  display OCC objects and dump them.

- TKIVtkDraw provides also test commands: ivtlinit, ivtkdisplay, ivtkerase, ivtksetdispmode,
   ivtksetselmode, ivtkmoveto, ivtkselect, ivtkfit, ivtkdump, ivtkbgcolor.

Corrected offscreen rendering mode.

Moved vinit command from /v3d/begin script to avoid unused occ view in ivtk tests.

197ac94e72 0024413: Visualization - get rid of projection shift from orthographic camera definition
From now on, the panning behavior of V3d_View completely corresponds to equal operations with camera. There is no more confusing "Center" property and "ProjectionShift" which were used to introduce composite panning, while respecting view referential points: At, Eye unchanged. The V3d_View::FitAll approach has been rewritten to do "fit all" geometrically, operating with frustum, to make it working for both orthographic and perspective projections.

1) Getting rid of ProjectionShift and Center property:
- Removed ProjectionShift property of Graphic3d_Camera.
- Removed confusing Center property of V3d_View (related to projection shift).
- Removed redundant code related to the Center property of V3d_View.
- Removed WindowLimit method of Graphic3d_Camera - no more used.

2) Improvements of fit all and selector:
- Improved FitAll operation of V3d_View and reused it in NIS_View - the perspective projection is now handled correctly.
- Revised code of Select3D_Projector class - can be defined with any given projection and model-view matrices.
- Modified StdSelect_ViewerSelector3d and ensured that panning, zooming and going into the view do not lead to unwanted re-projection of sensitives. The handling of perspective selection is revised.
- Take into account graphical boundaries of infinite structure on ZFitAll.

3) Improvements of camera:
- Introduced new z range scale parameter for V3d_View::AutoZFit. See, V3d_View::AutoZFitMode.
- Allow negative ZNear, ZFar for orthographic camera to avoid clipping of viewed model.
- Moved camera ZNear, ZFar validity checks to V3d_View level.
- Use more meaningful Standard_ShortReal relative precision for ZNear, ZFar ranges computed by ZFitAll.
- Use Standard_Real type for camera projection and orientation matrices.
- Extended camera to generate both Standard_Real and Standard_ShortReal transformation matrices using the same matrix evaluation methods and converted input parameters.

Correcting picking tests for perspective view
