Some old 2D games change palettes very frequently, which causes the
texture to be updated for each render.
This change uses a hash of the palette to detect changes, and include
the palette type in the cache key to distinguish textures of different
depth.
The GL renderer now detects the version of the current GL context and
compiles the shaders accordingly. Supports GLES2, GLES3 and desktop GL.
Android: use 8,8,8 framebuffer instead of 5,6,5. Requests a 8-bit
stencil buffer (modifier volumes)
The framebuffer is cleared by the background plane using global clipping
coordinates. This allows multiple rendering to different locations on
the framebuffer.
Fixes flashing menus in Vanishing Point, loading screens in Test Drive
Le Mans and Vigilante 8.
Better rear view mirror in Metropolis Street Racer.
Increase the size of RTT textures by a given integer factor. Defaults to
1.
This gives much better quality textures, particularly visible when used
fullscreen for transition or pause screens.
StrideSel and ScanOrder are no longer part of the texture cache key
since that breaks RTT texture matching. But they are updated at lookup
time so they will be used if the tex is updated later.
Fixes RTT-based xfade screens in Skies of Arcadia.
Paletted textures using a 32-bit palette and YUV textures are now
converted to 8888 format, which results in a lossless conversion.
Fixes background texture quality in Alone in the Dark.
In flat shading mode, the third vertex of a triangle defines its color
so we must maintain its index.
Fixes the remaining color polygons seen in Evolution - The World of
Sacred Device.
The previous algorithm to determine the sort mode for TR polys was
faulty. And the sort mode can vary between passes for multipass
rendering. This also removes the need for the hack to support Always
depth mode with autosorted TR polys. Should fix the Resident Evil 3 menu
problem.
Parse modifier volumes similarily to other polys (first, count, params).
Draw all triangles in one shot and use quad to sum up instead of
redrawing entire strip. Use OR operation for open volumes/quads
(Soulcalibur).
There's a texture corruption of the tennis ball and other textures,
notably the players' bags in the first intro sequence. The corruption is
due to render to texture squashing existing textures. Not sure what's
going on but this avoids the texture corruption. The original problem
remains.
