Applications should not destroy the HPS or HBITMAP. Applications should not use GpiSetPalette to modify the HPS's color palette. Applications should not disassociate HPS from it's DC, or unset the bitmap from HPS.Applications should not set any PS size, units and format using GpiSetPS. In other words, "Look, but don't touch!" See pglWaitPM and pglWaitGL for integrating OpenGL andGpi drawing. Applications should call pglReleaseFrontBitmap as soon as possible after locking the bitmap with this call.
