2015-08-21tdf#93547 - Disable OpenGL if we have a SEGV on windows in that code.Michael Meeks
Annotate when we are in an OpenGL rendering zone. Check for this in the VCL signal handler, and force OpenGL off here if exception occurred inside an OpenGL code-path.

2015-07-10vcl: move resample kernel classes out of bitmap.hxxMichael Stahl
Since commit f31e6debfa7e330f985a0846a6ca91130d3dab20 this drags in ridiculous amounts of boost headers, for probably negigible improvemnts of sin(x)/x for tiny x values. The compile time impact was not negligible, moving this nonsense to its own header removes 1.79 GB of preprocessor input from a full build. Change-Id: Ic41b2210eac8b130726610f2dbdbb449379225d1
2015-07-09opengl: use MVP matrix in vertex shaders, pixel offsetsTomaž Vajngerl
ChangChange all vertex shaders to accept model, view, projection matrix to calculate the vertex position. So now we don't need to convert the coordinates to OpenGL coordinate space [-1.0, 1.0] anymore. Additionally make it possible to offset vertex coordinates so we can apply 0.5 px offset (to hit the pixel center) at some operations. Change-Id: I8e0a61d5fd4ab6aaa1c0c94439061725918577a0

2015-01-27when drawing a transformed bitmap in opengl backend, scale it betterLuboš Luňák
The plain scaling is rather rough, and in fact drawing a scaled bitmap the normal way gives much better results (because OutputDevice pre-scales the bitmap before it's drawn). This one may be a bit slow perhaps, but hopefully nobody there's no code that'd extensively use bitmap drawing with custom transformations (wishful thinking).

2014-11-18vcl: since we share Bitmaps across all GLContexts simplify lifecycle.Michael Meeks
~X11SalVirtualDevice() was destroying X resources referred to by OpenGLSalBitmap's mpContext, which were subsequently accessed by Bitmap::AcquireReadAccess on the floating Bitmap. Better to use the default window's GLContext for all bitmap operations. Change-Id: I9009980e791cff1a1f36d626592d72c7a32efd39
