Common::fill fills up to but not including the address of the last item
Previously the last item of array v was not filled with 0, so if the rest of the code in the scaleLine() method did not update it, it would have a random init value which could cause segmentation fault when using the scale() method.
We use functions from GL_ARB_framebuffer_object extension and not from
GL_EXT_framebuffer_object where functions are suffixed by EXT.
This avoids crashes on implementations supporting only the EXT version.
OGLES2 doesn't support uniform booleans so we use macros to make it use
integers in this case. For other platforms, this change should be a
noop.
OGLES2 doesn't like float suffix for constants, remove it as well.
Add a class to group all renderer related (static) functions.
This allows to have getBestMatchingAvailableType inline in all engines.
The matching code is now shared between all engines but allows
customization for engines needing it (Grim, WME3D).
The new code takes runtime availability of features to select the
best renderer.
It avoid crashes when user choosed OpenGL but GLES2 is used.
Apple's desktop operating system was formerly called "Mac OS X" and "OS X", but since 2016 it has been called "macOS" (starting with version 10.12).
Changing across all comments and documentation to use this current terminology, except in cases where the historical versions are explicitly referenced. No code changes are made; we should consider changing those in future PRs.
With GLAD it's not needed anymore to link against OpenGL libraries.
As configure knows better whether a platform supports GLAD, detection is
moved here.
To allow platforms where OpenGL should be linked at build time, the
tests are kept. Android uses them for now.
The OpenGL for Games was completely decoupled from the OpenGL for 2D
engines. This not the case anymore.
Surface::create already initialized memory to 0 and getPixels can be
nullptr if bitmap size is 0. In this case memset gets called with
nullptr which is undefined behaviour.
This is considered as a good practice to not have relocations in text
segment.
The binary is now completely PIC and can easily be relocated at any
address (ASLR).
