Graphic3d_AspectFillArea3d now stores array of textures. Graphic3d_TextureParams stores texture unit for mapping texture. OpenGl_Context::BindTextures() - context now manages the set of active textures. Related code has been removed from OpenGl_Workspace. OpenGl_Sampler has been extended to hold texture parameters structure. OpenGl_Texture now holds OpenGl_Sampler instance as class field. OpenGl_Texture inherits new class OpenGl_NamedResource and holds texture identifier used for sharing resource in OpenGl_Context. OpenGl_RaytraceGeometry now creates bindless textures taking Sampler object directly from OpenGl_Texture. OpenGl_Context::BindTextures() automatically recreates immutable Sampler Object on texture parameters change. Declared new structure OpenGl_ArbSamplerObject for platform-neutral usage of related functionality. Related functions are now loaded within OpenGL ES 3.0+. Declarations.glsl - occActiveSampler has been renamed to occSampler0 with aliases occSamplerBaseColor (main) and occActiveSampler (for compatibility). Additional texture samplers should be declared explicitly within specific GLSL program as occSampler1, occSampler2, etc. AIS_Shape and AIS_ColoredShape now computes Shaded presentation with UV coordinates if texture mapping is enabled in Drawer. vshaderprog now accepts Shader source code as parameter.
