Summary	0023804: Unexpected color modulation during texture mapping
Description	AIS_TexturedShape seems to always create Graphic3d_AspectFillArea3d instance with some default material attributes (brass). As the result, unexpected modulate effect is observed between the texel color and material color (for brass ambient color is yellow - see attached screenshot), even if some different color is specified for the interactive object. Another minor issue is that there is no way in DRAW to disable color modulation for AIS_TexturedShape. It makes sense to improve vtexture or related command(s).
Steps To Reproduce	pload ALL box b 100 100 100 vinit vdisplay b vfit vsetdispmode b 1 vsetmaterial b plastic vsetcolor b ANTIQUEWHITE # After this line, the textured shape appears with yellow ambient color vtexture b 3 # This line has no effect vsetcolor b ANTIQUEWHITE
