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.

d509e5a43f 0027731: Visualization, OpenGl_AspectMarker - handle fractional marker Scale when sharing resources
OpenGl_AspectMarker::Resources::SpriteKeys() now encodes decimal number of marker scale into resource key,
since built-in markers are defined with 0.5 scale step.

fd59283a7b 0027633: Visualization, TKOpenGl - point sprites are inconsistent within Core and Compatible Profiles
OpenGl_ShaderManager::pointSpriteAlphaSrc() now does not return alpha from Red channel
for RGBA marker texture in Core profile.
OpenGl_ShaderManager::prepareStdProgramFlat() - restored code for drawing points without texture.

Built-in GLSL programs now flip .y in shaders instead of
relying on GL_POINT_SPRITE_COORD_ORIGIN unavailable on OpenGL ES.

Added sample markers.tcl (moved from test cases).
Sample now includes marker_kr.png for testing marker orientation.
