e3c26851dc Improve rendering performance on some GPUs 
This change sets textures filtering to GL_NEAREST by default. GL_LINEAR
filtering is only used when textures are transformed with a scale or
a rotation. This helps save a couple of fps on some GPUs.

e3095e0c1e Apply 3D transformations to gradient shaders. 
This fixes only linear gradients. Sweep and radial gradients, as well as
bitmap shaders, will be fixed in a future commit.

9cccc2b9bd Enforce maximum texture size. 
When an app tries to render a bitmap or path larger than the GPU's maximum
texture size, the drawing command is ignored and a warning is logged. This
change also makes texture drawing more robust by catching potential errors
during texture creation.

This change also fixes a crash in the FontRenderer. The destructor would
sometimes try to free an uninitialized array.

06f96e2652 Refactor Skia shaders handling. 
With this change, Skia shaders can easily be applied to any mesh. This change also
supports ComposeShader. For instance, this can be used to blend a gradient and a
bitmap togehter and paint a string of text with the result.
