0029902: Data Exchange, XCAF - provide extended Material definition for visualization purposes

Introduced new attribute XCAFDoc_VisMaterial storing visualization material definition.

XCAFPrs_Style has been exteneded Material() property.
XCAFPrs_AISObject::DispatchStyles() maps new XCAFPrs_Style::Material() property onto graphics aspects.

RWGltf_GltfJsonParser and RWObj_CafReader now put Material definition into XCAF document instead of a color label.
RWGltf_MaterialMetallicRoughness - added missing properties AlphaMode, AlphaCutOff and IsDoubleSided;
fixed default values in constructor for Metallic and Roughness.

Added commands XGetAllVisMaterials, XGetVisMaterial, XAddVisMaterial,
XRemoveVisMaterial, XSetVisMaterial, XUnsetVisMaterial for working with
new visualization materials table in the document.

kgv [Thu, 29 Aug 2019 08:04:56 +0000]
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.

kgv [Mon, 16 Sep 2019 20:06:38 +0000]
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.

New enum OSD_SignalMode describes different modes of signal handlers setting used in extended version of OSD::SetSignal().
Method OSD::SignalMode() returns mode set by the last call to SetSignal().
