Major Cooke b6b122b1e6 Added ability to change overlay alphas independently and renderstyles. ... - A_OverlayRenderStyle(int layer, int style) - Sets the renderstyle of a layer to one of the STYLE_ types. - A_OverlayAlpha(int layer, float alphaset) - Sets the alpha of a layer. - OverlayAlpha(int layer) - Non-action function retrieves the alpha of a layer. New overlay flags: - PSPF_ALPHA/STYLE - enables individual alpha and render styles on the layers set with them. - PSPF_FORCE(ALPHA/STYLE) - Forces the overlay's alpha to be rendered with its own amount instead of multiplying. This does not count towards fuzzy, transsouls, or stencil (use stenciladd, etc. for stencil). - PSPF_FLIP - Flips the X of the layer over, drawing it in reverse.		2016-10-10 10:11:32 -05:00

CMakeLists.txt	- Bump CMake version requirement to 2.8.7. This means that generator expressions must be supported as well as empty else and endif expressions (like most sane languages). ZDoom probably didn't work with 2.4 anymore anyway.	2016-02-05 21:19:29 -05:00
