Jonas Kulla e858bbdcf5 Lift 'Disposable' concept from core into bindings
Instead of replicating the RGSS Disposable interface in C++
and merely binding it, redefine the 'disposed' state as the
entire core object being deleted (and the binding object's
private pointer being null).

This makes the behavior more accurate in regard to RMXP.
It is now for example possible to subclass disposable classes
and access their 'dispose'/'disposed?' methods without
initializing the base class first (because the internal pointer
is simply null before initialization). Accessing any other
base methods will still raise an exception.

There are some quirks and irregular behavior in RMXP; eg.
most nullable bitmap attributes of disposable classes
(Sprite, Plane etc.) can still be queried afterwards, but
some cannot (Tilemap#tileset), and disposing certain
attributes crashes RMXP entirely (Tilemap#autotiles[n]).
mkxp tries to behave as close possible, but will be more
lenient some circumstances.

To the core, disposed bitmap attributes will look
identically to null, which slightly diverges from RMXP
(where they're treated as still existing, but aren't drawn).
The Disposable interface has been retained containing a
single signal, for the binding to inform core when
objects are disposed (so active attributes can be set to null).

Jonas Kulla 6bbdf7e183 Bitmap#blt: Clamp source rect to source bitmap bounds
RGSS allows the source rectangle in both `blt` and
`stretch_blt` to lie outside the source bitmap bounds
(treating the missing data as (0, 0, 0, 0)) and to be
inverted (in which case the blitted image is also inverted).

This commit only hanldes a corner case that
arises in the game "Last Scenario"; emulating the full
RGSS behavior is however desirable.

Jonas Kulla 6c481e5eb8 Eliminate GLEW dependency
GL entrypoint resolution is now done manually. This has a couple
immediate benefits, such as not having to retrieve hundreds of
functions pointers that we'll never use. It's also nice to have
an exact overview of all the entrypoints used by mkxp.

This change allows mkxp to run fine with core contexts, not sure
how relevant that is going to be in the future.

What's noteworthy is that  _all_ entrypoints, even the ones core
in 1.1 and guaranteed to be in every libGL, are resolved
dynamically.
This has the added benefit of not having to link directly against
libGL anymore, which also cleans up the output of `ldd` quite
a bit (SDL2 loads most system deps dynamically at runtime).

GL headers are still required at build time.

Jonas Kulla e0a4dfe372 Bitmap: Make #get_pixel/#set_pixel more accurate
This gets rid of the "batch/flush" semantics for #set_pixel
and instead just directly uploads the pixel color to the
texture, circumventing the float conversion entirely.
Also makes a lot of code simpler in many places as calling
'flush()' is no longer required for bitmaps.

Jonas Kulla b6a299541f Bitmap: Fix #get_pixel returning bogus values
We never bound the Bitmap FBO to the READ binding point,
so glReadPixels was blindly reading data off of whatever
was last bound there.

Jonas Kulla 2adf8ab265 Transition from QtCore to stdc++ / STL / boost
This looks like a pretty major change, but in reality,
80% of it is just renames of types and corresponding
methods.

The config parsing code has been completely replaced
with a boost::program_options based version. This
means that the config file format slightly changed
(checkout the updated README).

I still expect there to be bugs / unforseen events.
Those should be fixed in follow up commits.

Also, finally reverted back to using pkg-config to
locate and link libruby. Yay for less hacks!

Jonas Kulla 231e38ae8e Replace QVector, QList with std::vector, std::list

Also replace 'int' with 'size_t' where it is used only
as an array index.

Jonas Kulla ef2430e0c3 Sanitize #include statements
The general rule I'm aiming for is to <> include
system wide / installed paths / generally everything
that's outside the git managed source tree (this means
mruby paths too!), and "" include everything else,
ie. local mkxp headers.

The only current exception are the mri headers, which
all have './' at their front as to not clash with
system wide ruby headers. I'm leaving them be for now
until I can come up with a better general solution.

Jonas Kulla 9f26ff9fb0 Port over Bitmap 'radial_blur' from old SFML codebase
This implementation is also heaps better than the old
one as it doesn't use a (differently sized) aux texture,
meaning the Bitmap discards its old texture and aquires
one of same size, making reuse through the TexPool a
lot more likely. It also saves on the aux texture blits
and binding switches.

As the setup / resource acquisition far outweighs the
actual rendering cost, operation time is relatively
constant no matter how many divisions are used.

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.
