// Some notes:
//
// If mSWTexture==NULL, no texture is selected and pure white can be substituted (clipped to
// the current material color).
//
// If mAlphaMode!=mAlphaModeOn, then there's no need to do any alpha rendering, period.
// All alpha, even in textures with it, should be ignored. Otherwise, Alpha basically
// boils down to: texture pixel alpha * mClippedMaterial.diffuse.a
//
// The current material is stored in mClippedMaterial. You only need to ref the
// diffuse color:
// mClippedMaterial.diffuse.a
// mClippedMaterial.diffuse.r
// mClippedMaterial.diffuse.g
// mClippedMaterial.diffuse.b
//
// The triangle cull can one one of three things:
// mCullMode=mCullModeNone (cull no triangles)
// mCullMode=mCullModeCW (cull CW triangles)
// mCullMode=mCullModeCCW (cull CCW triangles)
//
// Texture clamping
// For this implementation, all uv coordinates will be between 0-1. However, in DirectX, it
// is sometimes necessary to clamp textures in order to prevent pixel bleed. So, though you
// won't need to implement any texture clamping, please put a few notes in for us so that we
// can later flesh it out if we decide the software renderer is fast enough to handle something
// like Hamsterball.
//
// Clipping
// There is a RECT structure defined called mClipArea. Rect is x,y,width,height -- it's NOT in
// x1,y1,x2,y2 format. Anything outside of that rect should just not be clipped. If you decide
// it's easier to clip against clip planes using a transform, then please scroll up to look at
// the Clip() functions-- they translate the coordinates into clip planes.
// SPECIAL NOTE: The clipping is in "absolute" coordinates. It is not in a 640x480 capable
// format. Our framework allows us to specify a 'real' resolution to use, and conforms everything
// down to whatever the screen is displaying. So, we usually use 800x600 for absolute resolution in
// game.
//
// So, to turn the clip rectangle into the "screen resolution" from "page resolution" (page is what

// int aLeft=mClipArea.mX*mPageWidthAdjust;
