Modify texture mapping settings

Texture sizes are limited to 1024x1024 texels in general.

Triangle mapping and perspective warp operations

d2_s32 d2_utility_fbblitcopy( d2_device * handle,
d2_u16 width,
d2_u16 height,
d2_blitpos srcx,
d2_blitpos srcy,
d2_blitpos dstx,
d2_blitpos dsty,
d2_u32 flags )

Copy a rectangular part inside the current framebuffer.

d2_s32 d2_utility_maptriangle( d2_device * handle,
const d2_f32 * points,
const d2_f32 * uvs )

This function uses d2_settexturemapping to map a texture on a triangle.

d2_s32 d2_utility_perspectivewarp( d2_device * handle,
d2_u16 srcwidth,
d2_u16 srcheight,
d2_s16 srcx,
d2_s16 srcy,
d2_s16 dstwidth,
d2_s16 dstheight,
d2_s16 dstx,
d2_s16 dsty,
d2_u16 wt )

Copies an image in perspective manner to a destination rectangle.

Framebuffer and view specific functions.

d2_s32 d2_writetexclut_direct( d2_device * handle,
const d2_color * clut_part,
d2_u32 start_index,
d2_u32 length )

Write a part of the color lookup table directly to the render buffer.
