- fixed color mask for green/magenta.
- fixed crash when initializing video, because it was accessing 'screen' before it was set from within the framebuffer's constructor.
Ultimately all this needs is a small data table describing the geometric properties of each mode and a single Present function that calls the mode specific variants.
Code size got reduced from 50kb to less than 20kb with proper separation of the generic parts from the OpenGL parts.
Like Linux and macOS this will only support borderless fullscreen in the active desktop resolution now, which is what modern systems need.
The list of discrete resolutions has been removed as it makes no sense anymore with a fixed video mode - all the other scaling options remain active, though.
This removes 3 uniforms, consisting of 9 floats. Those were merged into other values that never get used at the same time.
It also moves the costly setup of the fixed colormap out of the render state into the 2D processing code.
Since 3D forces use of render buffers now, it is no longer necessary to draw the entire scene with the colormap active, meaning it can be handled more efficiently.
Game code should never ever call the renderer directly. This must be done through the video interface so that it can also work with other framebuffers later.
These files are not part of the actual renderer but part of the system code.
This means, for separated modern and legacy GL renderers, there still will only be one set of this, unlike everything else.
This is better be made part of the 2D interface.
That would have been done long ago if it hadn't been for the totally incompatible way this was handled by the purely paletted software renderer.
Now with that out of the way there is no point keeping this code this deeply embedded in the renderer.
Lots of this was still laid out for DirectDraw. This removes most of Begin2D so that it can be done more cleanlz.
Note that this commit renders weapon sprites and screen blends incorrectly. Those will be fixed in an upcoming commit.
- eliminated hqresize.cpp's dependency on GL headers.
- cleaned up the logic for CreateTexBuffer so that hqresize.cpp does not need to check for software warped textures anymore.
The most frequent call using this is the regular texture creation function where this results in a pointless allocation and destruction of a temporary string which is easily avoided.
- with renderers freely switchable, some shortcuts in the 3D floor code had to be removed, because now the hardware renderer can get FF_THISINSIDE-flagged 3D floors.
- changed handling of attenuated lights in the legacy renderer to be adjusted when being rendered instead of when being spawned. For the software renderer the light needs to retain its original values.
