Functions
Buffer of select ID's
uint *	DRW_select_buffer_read (Depsgraph depsgraph, ARegion region, View3D v3d, const rcti rect, uint *r_buf_len)

Select Bitmap from ID's
Given a buffer of select ID's, fill in a booleans (true/false) per index. BLI_bitmap is used for memory efficiency.

Find Single Select ID's
Given a buffer of select ID's, find the a single select id.
