2016-03-16OPENGL: Handle GLES2 and GL shaders uniformly.Johannes Schickel
GLES2 requires precision qualifiers to be set and allows use of precision qualifiers. For GLES2 we define a default precision now. Since precision qualifiers are not supported in the GLSL version we use for GL, we introduce compatibility #defines.
2016-03-16OPENGL: Accelerate palette lookups with shaders.Johannes Schickel
This currently is limited to GL contexts.
2016-03-16OPENGL: Introduce simple abstraction for surfaces.Johannes Schickel
This is basically an interface extracted from Texture without any knowledge about any actual implementation, except for copyRectToTexture, fill, and dirty rect handling. These are convenient helpers.
2016-03-16OPENGL: Cleanup. Remove Texture::getHardwareFormat.Johannes Schickel
2016-03-16OPENGL: Move color key handling for CLUT8 to TextureCLUT8.Johannes Schickel
2016-03-16OPENGL: Fix texture format for BGR565.Johannes Schickel
2016-03-16OPENGL: Move max texture size information to Context.Johannes Schickel
2016-03-16OPENGL: Create new abstraction for GL texture objects.Johannes Schickel
2016-03-16OPENGL: Remove (some) unused GL definitions.Johannes Schickel
2016-03-16OPENGLSDL: Request "standard" GL contexts.Johannes Schickel
Compatibility profiles only exist in modern OpenGL and we request an ancient version.
2016-03-16OPENGL: Unify shader implementation for GL and GLES2.Johannes Schickel
2016-03-16OPENGL: Slightly cleanup programmable pipeline handling.Johannes Schickel
2016-03-16OPENGL: (Partly) move context specific handling to Context.Johannes Schickel
This does not include (most) shader setup, and projection matrices yet.
2016-03-16OPENGL: Make Context::reset explicitly reset state.Johannes Schickel
2016-03-16OPENGL: Slight simplifcation for opengl-func.h usage.Johannes Schickel
2016-03-16OPENGLSDL: Destroy GL context on exit with SDL2.Johannes Schickel
2016-03-16OPENGL: Handle destruction gracefully when no context is setup.Johannes Schickel
2016-03-16OPENGL: Add support for shaders with GL contexts.Johannes Schickel
2016-03-16OPENGL: Reset context description on context destroy.Johannes Schickel
2016-03-16OPENGL: Reset full context structure.Johannes Schickel
2016-03-16OPENGL: Support GLES2 contexts.Johannes Schickel
2016-03-16OPENGL: Typo.Johannes Schickel
2016-03-16OPENGL: Simplify orthogonal projection setup.Johannes Schickel
2016-03-16OPENGLSDL: Slight cleanup.Johannes Schickel
2016-03-16OPENGL: Simplify context type setting.Johannes Schickel
2016-03-16OPENGLSDL: Try to use GL(ES) context SDL2 defaults to.Johannes Schickel
2016-03-16OPENGL: Support RGB555 for OpenGL ES output.Johannes Schickel
This mode should *not* be used by any new engines/code. If someone is going to use it and says it works with the OpenGL output, please make them wear a red uniform and beam them onto a remote planet.
2016-03-16OPENGL: Allow runtime specification of OpenGL mode.Johannes Schickel
Formerly, we required that the OpenGL mode was fixed at compile time. Now we allow the code to work with whatever it is given at runtime. It is still possible to force a context type on compile time.
2016-03-16OPENGL: Remove support for ARGB8888.Johannes Schickel
This used to be used by Sword25. Since it is not supported by GLES and no engine code uses it we drop support. Hopefully, this helps people to realize they should not use that format in their engine.
2016-03-16OPENGL: Rename GLCALL to GL_CALL.Johannes Schickel
2016-03-16OPENGL: Resolve OpenGL functions on run-time.Johannes Schickel
Formerly we relied on static linkage. However, in the presense of modern OpenGL (ES) implementations it is not easily identifable which library to link against. For example, on Linux amd64 with nVidia drivers and SDL2 setup to create a GLES 1.1 context one would need to link against libGL.so. However, traditionally GLES 1.1 required to link against libGLESv1_CM.so. To prevent a huge mess we simply resolve the OpenGL functions on run-time now and stop linking against a static library (in most cases). GLES support needs to be enabled manually on configure time for now. Tizen changes have NOT been tested.
2016-03-16OPENGL: Define GLCALL in opengl-sys.h.Johannes Schickel
debug.h is now always included and all calls should be made through GLCALL.
2016-03-16OPENGL: Add functionality to query OpenGL functions on runtime.Johannes Schickel
This can and will be used for future extension usage support. Tizen changes have been untested.
2016-03-16OPENGL: Refactor GL extension handling slightly.Johannes Schickel
2016-03-15MACOSX: Add comment about track ID search loop.Johannes Schickel
2016-03-15LINUX: Guard Linux audio CD code.Johannes Schickel
2016-03-15MACOSX: Guard audio cd code by define check.Johannes Schickel
2016-03-15MACOSX: Replace manual uint parsing by strtol.Johannes Schickel
2016-03-14WIN32: Cleanup header includes for AudioCD code.Johannes Schickel
2016-03-14WIN32: Supply required DDK headers for older MSVC.Johannes Schickel
Header file taken from MinGW's w32api 4.0.3.
2016-03-13WIN32: Fix compilation with MinGW-w64.Johannes Schickel
2016-03-13WIN32: Guard AudioCD code by WIN32 check.Johannes Schickel
2016-03-13WIN32: Silence warning in AudioCD code.Johannes Schickel
2016-03-13WIN32: Fix AudioCD compilation.Johannes Schickel
2016-03-13BACKENDS: Fill buffer at start of AudioCD playback.Johannes Schickel
As suggested by clone2727.
2016-03-13POSIX: Cleanup AudioCD manager creation.Johannes Schickel
2016-03-13BACKENDS: Add ScummVM license header for AudioCD code.Johannes Schickel
As discussed with clone2727.
2016-03-13SDL: Get rid of reference to SDL 1.3.Johannes Schickel
We only support SDL 1.2 and SDL 2.
2016-03-13BACKENDS: Formatting fixes.Johannes Schickel
2016-03-13BACKENDS: Switch to CDROMREADRAW for Linux audio CDMatthew Hoops
CDROMREADAUDIO seems to crash the kernel when ejecting while playing. Let's try to avoid that.
