It used to +be called during state update in order to determine if the driver +could do glLogicOp() operations, and if not, set the SWLogicOpEnabled +flag. Drivers should instead examine the LogicOp state themselves +and choose specialized point, line, and triangle functions appropriately, +or fall back to software rendering. The Xlib driver was the only driver +to use this function. And since the Xlib driver no longer draws +points, lines or triangles using Xlib, the LogicOp function isn't needed. + + +The ctx->Driver.IndexMask() and ctx->Driver.ColorMask() functions +are now just called from glIndexMask and glColorMask like the other +GL state-changing functions. They are no longer called from inside +gl_update_state(). Also, they now return void. The change was made +mostly for sake of uniformity. + + + ---------------------------------------------------------------------- -$Id: RELNOTES-3.5,v 1.2 2000/08/31 23:04:17 brianp Exp $ +$Id: RELNOTES-3.5,v 1.3 2000/09/07 15:46:05 brianp Exp $ |
