Jonas Kulla 4ff563725b Make 'rb_get_args()' va_arg passing safer by introducing a termination marker
What can I say. I made a pact with the devil, and paid dearly.
Almost a whole day's worth of debugging, actually. Not again.

If this turns out to be slow we can always optimize the critical
parts (with no variable param count) later, or completely remove it.

Also make it a tad faster.

Jonas Kulla 97d0794c7c Remove Serializable's virtual destructor. It didn't do anything anyway.
To still make the compiler happy, add virtual destructors
to all descendants of Serializable.

Jonas Kulla dff2d79a70 Implement blits from mega surfaces to regular Bitmaps
This is used in events that take their sprite from a tile
out of the tileset.

Jonas Kulla 32361e513a Track 'tainted' area of Bitmaps to optimize blit operations
The 'tainted' area of a Bitmap describes what parts are no
longer in a 'cleared' state. When we blit to a fully cleared
are of a Bitmap at full opacity, we can completely disregard
the existing pixels in the operation, meaning we can skip any
blending calculations and just blit / upload straight to the
texture. This greatly speeds up text message rendering.

In the process, pixman has become a new dependency for mkxp,
but the results of this optimization are well worth it!

Jonas Kulla 10ec55e39b Implement a new tileset atlas layout to allow for bigger tilesets
The atlas packing algorithm has been reworked to pack autotiles
and tileset very efficiently into a texture, splitting the tileset
in multiple ways and eliminating the previous duplication of image
data in the atlas across "frames". Animation, which these frames
were designed for, is now done via duplicated buffer frames,
ie. each animation frame has its own VBO and IBO data. This was
not done to save on VRAM (hardly less memory is used), but to
make place for the new atlas layout.
Thanks to this new layout, even with a max texture size of 2048,
one can use tilesets with up to 15000 height. Of course, such
a tileset couldn't be stored in a regular Bitmap to begin with,
which is why I also introduced a hack called "mega surfaces":
software surfaces stored in RAM and wrapped inside a Bitmap,
whose sole purpose is to be passed to a Tilemap as tilesets.

Various other minor changes and fixes are included.

Jonas Kulla 9e63fb6b64 Remove the remaining bits of deprecated GL usage
The drawing is now completely shader based, which makes away
with all usage of the depracted matrix stack. This also allows
us to do things like simple translations and texture coordinate
translation directly instead of doing everything indirectly
through matrices.

Fixed vertex attributes ('vertexPointer()' etc) are also
replaced with user defined attribute arrays.
