This is a generic way to get matrix data to shaders without using
(old-school) uniforms. This is another step towards more compatibility
with how new APIs (Vulkan) do things to increase the odds for a Vulkan
port at some point.
This fixes a CTD when FRED is started since the graphics function
pointers are not valid at that point which causes a null pointer
dereference when starting FRED. This fixes that by checking if the
graphics system has been initialized before calling that function.
This fixes#1483.
This uses UBOs for building a buffer object of uniform data before
using that data to draw objects. This should reduce the CPU overhead by
reducing the amount of glUniform calls required for executing a single
draw call. This is especially useful if rendering is limited by the CPU
which should help performance for people with slower CPUs.
This fixes#910.
This restores the behavior from before the matrix system changes. The
observed behavior is more or less the desired behavior sinde setting the
2D projection matrix resets the model matrix stack but it happens to
work with the previous movie code since the 2D matrix is not set if no
perspective projection matrix was set before. This would need to be
fixed if the movie player should ever work within a mission but for now
this will fix the reported bug.
All transformations are now handled by shaders so there is nothing
special going on in the graphics API specific code anymore. Since model
uniform buffers require access to these matrices I moved the matrix
handling out of the graphics API code.
