m_textureNPOT and m_limitedNPOT have not been initialized in the ctor resulting in
m_limitedNPOT being incorrectly being true sometimes for Intel drivers. For other
drivers the value had been set.
A few more getters for parsed information are added to GlPlatform.
This includes the driver information retrieved through glGetString
and information like direct rendering and loose binding.
Additionally the methods to convert version, driver and chipClass
to string are added to the public interface.
These changes allow parts outside GlPlatform to get the same debug
information about the GL system.
There seems to be a problem with nouveau GLES if you want to create an
EGLImageKHR more than once in a frame for the same pixmap. This patch
circumvents the problem in the way that it implements tfp the same way
as the mesa example in
mesa/demos/src/egl/opengles1/texture_from_pixmap.c does it. A nice
side effect of this is that it also avoids the overhead of recreating
the texture for every damaged window.
REVIEW: 103303
Fixes a major regression which allowed OpenGL
compositing to be used with software rasterizer, which
either did not work or crashed directly.
Cherry-picked from cf2f572 in branch KDE/4.7.
Adding a new method to retrieve whether the OpenGL implementation
uses any kind of software emulation and no software emulation can
provide GLSL support, even if it claims so.
Thanks to Maurel for testing again and again proposed patches.
BUG: 271166
Second part of cleaning up the lib directory: the effects library
now lives in libkwineffects/ directory.
For existing effects nothing changes as the install path is unchanged.
The change obsoletes the lib/ directory.
As glplatform.h has not yet been exported I dared to export it and
adjust the places where it is used.
