The previous version used NanoVG which caused quite a serious FPS drop.
This adds a buffer batching class which groups line drawing operations
together and submits them to the GPU with a single draw call.
This adds proper Unicode support by allowing the parse system to read
UTF-8 encoded files. The new mode is controlled by a mod option which
allows older mods to continue using the legacy text encoding.
That option changes the behavior of several systems in FSO. It disallows
the usage of Volition fonts since they don't support Unicode encoding
and changes a few usages of special characters to their unicode
counterparts of generic rendering solutions.
This fixes#1415.
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.
This was reported by @AxemP who wanted to have leading tabs in a text
line. However, split_str removed those characters by default since it
ignores leading whitespace. To fix that unexpected behavior of
gr.drawString I added a new paramter to split_str which disabled
whitespace removal and enabled that flag for the scripting function.
That should not be a problem for existing scripts since the expected
behavior would be that leading whitespace remains in place and since we
have not received any bug reports about missing white space I'm going to
assume that no one has used the function like this before removed those
characters by default since it ignores leading whitespace. To fix that
